Vesper's MEMS microphones represent a radical shift from the capacitive MEMS microphones that are shipping by the hundreds of millions in smartphones, hearables, smart speakers, Internet of Things devices and connected cars. Vesper's piezoelectric design is waterproof, dustproof, particle-resistant and shockproof. From the kitchen to the beach, piezoelectric MEMS microphones make voice-interface devices practical in any environment. They are also ideally suited for far-field applications such as microphone arrays.
